1) To suspend acceleration or deceleration automatically
Set the frequency with f350 or f352 and the time with f351 or f353 , and then set f349 to 1 .
When reached the set frequency, the motor stops accelerating or decelerating to run at a constant speed.

for an input terminal. As long as ON signals are inputted, the motor continues to rotate at a constant
speed.

Function No. 61 is the inversion signal.
Note: If the operation signal is ON after Acceleration/ deceleration suspend signal is ON, the inverter will operate
at frequency set with
f240 .

If the stall control function is activated during constant-speed rotation
The frequency changes momentarily as a result of stall control, but the time for which the frequency changes is
included in the suspend time.
